Comparing: Pz.Kpfw. III Ausf. K vs. M4 Improved

This tank was developed on the basis of the later Pz.Kpfw.III Ausf. J chassis, combining it with the Pz.Kpfw.IV Ausf. F2 turret and a 75-mm gun. The first design plans were completed by the end of December 1941. Manufacturing began, but the vehicle proved overly complex and production was soon canceled. A total of 50 vehicles were completed and used as command vehicles. They featured 50-mm guns; the 75-mm guns were never mounted.

A variant of the M4 medium tank with angled hull and turret armor. It was developed by the Detroit Arsenal in August 1942. The changes were intended to improve the tank’s protection without increasing weight or degrading other technical characteristics. Existed only in blueprints.
